A few lucky folks have now had their skin kissed by the light of alien suns. That light was generated here on Earth, at the world’s first “stellar tanning salon,” which opened this week at the Festival of the Future in Munich, Germany. The salon’s lamps simulate the spectra of a variety of stars, from […]
The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity indicates the halfway point of solar maximum, the height of solar activity, and the beginning of the shift toward solar minimum. The last […]

Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. The sun has a powerful magnetic field that creates sunspots on the star’s surface and unleashes solar storms such as the one that bathed much of the planet in beautiful auroras this month. But exactly how […]
By Will Dunham WASHINGTON (Reuters) – The sun’s magnetic field, which causes solar storms like the one that hit Earth this month and produced beautiful auroras, may originate at shallower depths in the star’s interior than previously thought, according to researchers. The sun’s outer 30% is comprised of an “ocean” of churning gases plunging more […]
CAPE CANAVERAL, Fla. (AP) — New research indicates the sun’s magnetic field originates much closer to the surface than previously thought, a finding that could help predict periods of extreme solar storms like the ones that slammed Earth earlier this month. The magnetic field appears to generate 20,000 miles (32,000 kilometers) beneath the sun’s surface. […]
As you might’ve heard, there’s a little bit of solar activity going on. Okay, a lot of solar activity. In fact, there’s been so much solar activity that some heliophysicists — not to mention laypeople waiting to witness the aurora — have probably not slept for the last week or so. Of course, space agencies across the […]
Reese Witherspoon does it all. She’s an actor, a producer, a mother and even owns multiple businesses (you may have heard of her clothing company, Draper James, or her media company, Hello Sunshine). And the 48-year-old still finds the time to hit red carpets in stylish outfits that we can’t stop thinking about. But you […]

Tremendous explosions in a galaxy close to the Milky Way are pouring material equivalent to around 50 million suns into its surroundings. Astronomers mapped this galactic pollution event in high resolution, obtaining important hints about how the space between galaxies becomes filled with chemical elements that eventually become the building blocks of new stars. The […]
Astronomers have, for the first time, detected stellar winds blowing from three main-sequence stars similar to the sun. The observation helped determine the rates at which these stars lose mass via their stellar winds, finding these winds shrink about 67 times as fast as the sun loses mass via its own solar winds. The team […]
